6.11.1 Configuring Manual Key Settings
A transform set is a combination of security protocols and algorithms applied to IPSec protected
traffic. During security association (SA) negotiation, both gateways agree to use a particular
transform set to protect data flow.
A transform set specifies one or two IPSec security protocols (either AH, ESP, or both) and specifies
the algorithms to use for the selected security protocol. If you specify an ESP protocol in a transform
set, specify just an ESP encryption transform or both an ESP encryption transform and an ESP
authentication transform.
When the particular transform set is used during negotiations for IPSec SAs, the entire transform set
(the combination of protocols, algorithms, and other settings) must match a transform set at the
remote end of the gateway.
Use the Manual Key Settings screen to specify the transform sets used for VPN access.
To configure manual key settings for the AP-5131:
1. Select Network Configuration -> WAN -> VPN from the AP-5131 menu tree.
2. Refer to the VPN Tunnel Config field, select the Manual Key Exchange radio button and
click the Manual Key Settings button.
IKE Settings After selecting Auto (IKE) Key Exchange, click the IKE Settings
button to open a screen where IKE specific settings can be
configured. For more information, see Configuring IKE Key Settings
on page 6-44.
